What Is Buddy Punching and How to Stop It

Buddy punching is when one employee clocks in on behalf of a colleague who hasn't arrived yet — or hasn't arrived at all. It's one of the most common forms of time theft in hourly-paid work, and it costs UK businesses an estimated hundreds of millions of pounds every year.

If your business relies on manual time sheets, a shared PIN-based clock-in machine, or even just "signing in," buddy punching is probably happening — whether you know it or not.

How Common Is Buddy Punching?

Studies consistently show that buddy punching is widespread. One frequently-cited survey found that 75% of businesses lose money to payroll fraud, with buddy punching being the most common form. UK figures are harder to pin down, but anecdotally, most hospitality managers who've switched to GPS-verified clock-in systems report a measurable drop in their wage costs almost immediately.

Even 15 minutes of extra pay per employee per day adds up fast. For a cafe with 8 part-time staff on £12/hour, that's nearly £300 a month disappearing through "ghost time."

How to Prevent Buddy Punching

The most effective ways to stop buddy punching require moving away from shared clock-in methods:

1. GPS-Verified Mobile Clock In

When staff clock in on their personal mobile phone, and the app verifies their GPS location, buddy punching becomes nearly impossible. Your colleague can't hand you their phone to clock in — and if they did, their device would need to be physically at the venue.

This is the approach ClockIt takes: every clock in includes a GPS location check. If someone tries to clock in from home on behalf of a colleague, the system flags it immediately.

2. Photo Capture at Clock In

Some clock-in systems capture a photo or selfie when staff clock in. This provides a timestamped visual record that can be audited if there's a dispute — and acts as a deterrent because staff know there's a record.

3. Remove Shared PIN Systems

Shared PIN clock-in machines are the easiest system to abuse. If everyone knows the PIN (and they do), buddy punching takes 10 seconds. Moving to individual mobile clock in eliminates this entirely.

4. Manager Alerts for Early Clock Ins

If staff can clock in 15 minutes before their shift "just in case," those extra minutes accumulate across dozens of shifts. Set your system to alert you or auto-reject clock ins before the scheduled start time.

Having the Conversation With Your Team

If you're introducing a GPS clock-in system partly to prevent buddy punching, you don't need to be confrontational about it. Frame it as improving accuracy for everyone — staff who were previously underpaid due to timesheet errors also benefit from more accurate records.

Most employees won't object to a fair, accurate time tracking system. The few who do object are often the ones worth paying attention to.
